From 47a72688fae7298e1ad5fdc9bff7e04b6a549620 Mon Sep 17 00:00:00 2001 From: Adrian McMenamin Date: Wed, 4 Mar 2009 00:31:04 +0000 Subject: mtd: flash mapping support for Dreamcast VMU. This patch adds support for the Sega Dreamcast visual memory unit as a flash mapping. It requires changes in the maple bus driver (posted separately) to support block reads and writes. The VMU is a 'smart' flash device, with a built-in 8-bit controller - for instance there is an erase before a write but it is hidden from the user. But the device's overall behaviour means it works well with the mtd layer and it is appropriate to add it as an mtd mapping.
